I am 23 weeks pregnant and have recently been kept up for hours at night as I simply cannot sleep. Have tried hot baths, swimming to tire myself, etc, but nothing works so far. I get up on average 5 times a night and am then exhausted the next day. A lot of this seems to be due to the fact that I cannot get into a comfortable position now that my stomach is expanding rapidly. Does anyone know of any tips? Also, does anyone know if I can talk melatonin to help me sleep. As it is herbal, not sure what I can or cannot do.
